Want to buy a jacket for the winter? Here's what's trendy

Every few seasons, menswear designers revive a dormant staple – this Autumn/Winter, it’s the double-breasted jacket. It was long in the Sixties, big and brash in the Seventies and four-buttoned and boxy in the Eighties. The modern version, however, is a slimmer construction, cut closer to the body (just like its single-breasted cousin) and six-buttoned.

Leather jackets, much like motorcycles, have always been a symbol of rebellion (think Steve McQueen’s Belstaff jacket or Brando’s badass Perfecto). This time around, though, leather assumed a life of its own: from bombers to three-piece suits and discreet detailing like patched accents, leather was treated to couture-level tailoring.

GQ tip: Go beyond the obvious Brando interpretations: Ditch the jeans and pair a bomber with a button-down shirt and formal trousers for a polished (yet rakish) vibe.

The coats

Coats complete a man’s winter wardrobe. This season, trenches get vibrant at Burberry, the long coat takes a new shape with Arjun Saluja, space jackets make an appearance at Louis Vuitton and Dior Homme lends a sporty touch to the military jacket. What we’re really digging, though, is the detailing – from brass buttons to faux fur.

GQ tip: Choose a length that suits your frame. Below the knee works for tall men; something shorter is better for the rest of us.
